NEET 2016 Phase 1 · ChemistryPrevious Year Question

Two electrons occupying the same orbital are distinguished by:

Answer: (D) Spin quantum number. \textbf{Answer:} (D) Spin quantum number \textbf{Solution:} Two electrons in the same orbital have identical $n$ , $l$ and $m_{l}$ values; they differ only in the spin quantum number ( $m_{s} = + \frac{1}{2}$ and $- \frac{1}{2}$ ), as required by the Pauli exclusion principle.
